To all whom it mag/concern:

Be it known that I, HENRY JANDER, a citizen of the United States of America, residing at Brooklyn, Kings count-y,- State of New York, have invented certain new and useful Improvements in Portable Trucks for Feeding Trays to Ovens, of which the following is a full, clear, and exact description.

This invention relates to improvements in portable trucks particularly arranged and designed for use in connection with baking ovens. One of the objects of my invention is to provide a truck, arranged to hold trays filled with articles to be baked, that is, adapted to be moved up to the doors of the oven and depressed or lowered at one end to permit the trays to be easily rolled off the truck into the ovens, special means being provided to lower or raise the said truck at one end thereof.

I will now proceed to describe my invention in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawings, forming part hereof, wherein Figure 1 is a side elevation of one embodiment of my invention, a portion of a baking oven being diagrammatically illustrated;

Fig. 2 is an enlarged vertical sectional view of the truck, the section being taken on a line 2-2 in Fig. 1, looking in the direction of the arrow;

Fig. 3 is a sectional plan view, the section being taken on a line 33 in Fig. 2; and

Fig. 4 is an enlarged fragmentary sectional View illustrating the manner of looking the trays to the truck.

As herein embodied my improvement comprises a portable truck consisting of the vertical side members 5, 5 and 6, 6, to which are secured angle-iron rails 7 slotted at one end thereof, as at 8, to receive the wheels 9 of a wheeled tray 10. In this instance I have illustrated six pairs of rails 7; hence the truck, as herein arranged, will accommodate six wheeled trays 10. The trays 10 are designed to carry the articles to be baked, such as loaves of bread, cake, etc.

The framework of the truck, namely, the vertical members 5, 5, 6, 6 and rails 7 are carried by a base-member 11 having Wheels 12, one end of the base-member carrying a vertical post 13, to which one end of the framework is slidably connected.

As has been stated, one end of the framework of the truck is arranged to be raised or lowered. Therefore,I secure the lower end of-each vertical frame-member 6 to the base-member 11, the opposite'end of the framework being free, that is to say, not connected to the base-member 11. To sli dably connect thefree end of the framework to the vertical posts, I provide the said framework with blocks 1. L which slidably engage the posts 13. To the said posts I permanently secure blocks 15 to which one end of a toggle-link 16 is pivotally secured. To each block 14 I pivotally secure one end of a coiiperating toggle-link 17, the said links 16 and 17 being pivotally connected together at 18. The toggle, consisting of the links 16 and 17, is operated by levers 19 and connecting-rods 20. When the levers 19 are operated the toggles can be opened or closed to raise or lower the adjacent end of the framework, the blocks 1d sliding upon the posts 13.

The trays 10 are made up of the wheels 9,

and wheels 21 at the opposite end of the tray-frame, consisting of the tray proper, indicated by 22, supported by the axles 23.

The trays 10 are designed to be wheeled onto or off the rails 7. WVhen positioned upon the rails the wheels 9 will rest within the slots 8, as indicated in Fig. 4; hence they will be held against movement or locked to the rails 7. When the trays are thus positioned the truck can be wheeled away from an oven, indicated by 24 Fig. 1, or up to the same or to another oven or to any desirable location without disturbing the trays. The wheels 21 of the trays will at all times rest upon the rails 7.

As herein illustrated, the truck is positioned to permit the trays to be rolled off onto the rails 25 of the oven 24; hence the end 26 thereof has been lowered by manipulating the handles 19 to break or open the toggle. When the truck is in this position the wheels 9 of the trays will be lifted out of the slots 8, after which the trays can be rolled ofi the rails 7 onto the rails 25 in the oven 2-1. It will of course be understood that the truck will be rolled up to the doors of the oven after the trays 10 have received be raised to cause the rails 7 their supply of articles-t0 be baked. While the truck is being Wheeled up to or away from the Oven, the end 26 of the truck will horizontal position. 7

What I claim as my inventionis: V

1. A truck consisting of a base-member, wheels carried thereby, a tray-frame secured at one end thereof to one end of said base-member, posts carried by the base- 1 member, and means to slidably connect said posts and the adjacent end ofthe trayframe. c

2. A truck consistingof a base-member, wheels carried thereby, a frame secured at one end thereof to said base-member, toggles connecting said base-member and the opposite end of the frame, independent posts supporting said toggles; meansto operate the toggles to raise or lower the frame, and wheeled trays carried by the frame.

to assume a 3. A portable truck consisting of a movable frame, Wheeled trays carried thereby, and rails for sald trays, sald rails bemg proyided with slots to receive the Wheels of said H trays to lock the trays against premature movement.

4. A truck consistifig of a base-member, Y

vertical posts carried thereby, a frame-work, blocks connected With said framework and slidably engaging the posts, toggles connecting said blocks and the posts, and a link and lever connection to operate the toggles, whereby one end of the framework can be raised or lowered.
